Well, I've taken the plunge, and disassembled my first IGH, an August 1963 SA-TCW-III coaster brake 3 speed. Well, I mostly took it apart. Some place I read not to move the drive side cone and lock nut, because if not in the exact place, the shifting will be affected. I also didn't bother to unthread the drive side "dohicky with the right hand threads" which holds the internal ring gear, etc., in place (I've yet to learn the proper SA parts vocabulary, but I'll work on this ).
I've read Mr. S. Brown and others about how unreliable the braking is on the TCWs. So I know what I'm getting myself into. The plan is to lace this to a Sun CR18 26 X 1 & 3/8 rim to match the front hub drum brake on this Motobecane mixte I'm building for my daughter. Also, along with the drum brake I'll leave the centerpull in place on the rear, so "triple" brakes.
I'm currently removing the the drop bars and SA-S5 five speed rear wheel. The plan is to make this a comfortable neighborhood bike with upright bars and simple three speed shifting.
So am I crazy? I manage to reassemble everything back together for a dry fit, and I believe I did it correctly. So should I leave it at this or go ahead and build the wheel?
